Local electronic structure of interstitial hydrogen in MgH inferred from muon study
R. Kadono, M. Hiraishi, H. Okabe +2
Magnesium hydride has great potential as a solid hydrogen (H) storage material because of its high H storage capacity of 7.6 wt%. However, its slow hydrogenation and dehydrogenatio…
Local spin dynamics in geometrically frustrated Mo pyrochlore antiferromagnet LuMoON
S. K. Dey, K. Ishida, H. Okabe +6
The magnetic ground state of oxynitride pyrochlore LuMoON, a candidate compound for the quantum spin liquid (, Mo), was studied by muon spin rotat…
Organic Molecular Dynamics and Charge-carrier Lifetime in Lead Iodide Perovskite MAPbI
A. Koda, H. Okabe, M. Hiraishi +4
The long charge carrier lifetime of the hybrid organic-inorganic perovskites (HOIPs) is the key for their remarkable performance as a solar cell material. The microscopic mechanism…
Pyrochlore Oxide Hg2Os2O7 on Verge of Metal-Insulator Boundary
Kota Kataoka, Daigorou Hirai, Akihiro Koda +3
Semimetallic osmium pyrochlore oxide Cd2Os2O7 undergoes a magnetic transition to an all-in-all-out (AIAO)-type order at 227 K, followed by a crossover to an AIAO insulator at aroun…
Ambipolar Property of Isolated Hydrogen in Oxide Materials Revealed by Muon
M. Hiraishi, H. Okabe, A. Koda +2
The study on the electronic state of muon as pseudo-hydrogen (represented by the elemental symbol Mu) has long been appreciated as one of the few methods to experimentally access t…
Dimensional reduction by geometrical frustration in a cubic antiferromagnet composed of tetrahedral clusters
Ryutaro Okuma, Maiko Kofu, Shinichiro Asai +10
Dimensionality is a critical factor in determining the properties of solids and is an apparent built-in character of the crystal structure. However, it can be an emergent and tunab…
